ARM: zynq: Enable capsule update for qspi and mmc
Generate dfu_alt_info setup at runtime for capsule update.
Enabling this feature will help with upgrading boards without remembering
what is where.
The similar change was done for ZynqMP by commit b86f43de0be0 ("xilinx:
zynqmp: Add support for runtime dfu_alt_info setup").
Code needs to be enabled by CONFIG_SET_DFU_ALT_INFO.
And also enable capsule on disk for RAW firmware images with efidebug
command.
Two indexes are supported for SPL flow. Images can be generated like:
./tools/mkeficapsule --raw spl/boot.bin --index 1 capsule1.bin
./tools/mkeficapsule --raw u-boot.img --index 2 capsule2.bin
Then place them to SD card and load them:
load mmc 0 10000000 capsule1.bin && efidebug capsule update -v 10000000
load mmc 0 10000000 capsule2.bin && efidebug capsule update -v 10000000
FSBL flow will also work where only index 1 capsule is used. There
should be enough space for using boot.bin with bitstream too.
Zynq also support multiple boot locations in SPI or MMC but it is not wired
by this patch.
